Features 

The side-folding stock makes storage and transport straightforward without adding much bulk. An adjustable cheek rest lets you set a consistent cheek weld for different shooters, and the flip-up sights allow quick target acquisition without mounting an optic. The .22 LR chambering keeps ammunition costs low and recoil nearly nonexistent, which makes the 22-round magazine useful for sustained range sessions.
